4 /* PCRE2 is written in Standard C, but there are a few non-standard things it
5 can cope with, allowing it to run on SunOS4 and other "close to standard"
8 In environments that support the GNU autotools, config.h.in is converted into
9 config.h by the "configure" script. In environments that use CMake,
10 config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
11 hand" without using "configure" or CMake, you should copy the distributed
12 config.h.generic to config.h, and edit the macro definitions to be the way you
13 need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
14 so that config.h is included at the start of every source.
16 Alternatively, you can avoid editing by using -D on the compiler command line
17 to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
18 but if you do, default values will be taken from config.h for non-boolean
19 macros that are not defined on the command line.
21 Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
22 defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
23 such macros are listed as a commented #undef in config.h.generic. Macros such
24 as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
25 surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
27 PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
28 HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
29 sure both macros are undefined; an emulation function will then be used. */
